基于PDIUSBD12的通用Fireware结构及设计

Universal Framework of Fireware and Its Design Based on PDIUSBD12

USB项目开发中,Fireware的设计是关键部分,它的效率决定了USB外设的数据传输速度,因此,一个高效、结构良好的固件可以大大降低USB设计的难度,提高外设的性能。分析了固件的工作原理,提出了模块化的分层结构模型,并给出了设计方法。

The design of Fireware is a key step in the process of which USB is applied in products. The transmission rate between equipments and computers through USB is decided by Fireware. So the difficulty of USB design can be great reduced and the performance of USB equipment can be improved by Fireware with a high efficiency and good framework, The paper analyzes the working principle of Fireware, introduces a model with modularizing level framework and design method.
